Si-Tex T-2041 4kW Radar with 25″ Radome

Improve safety and situational awareness aboard your vessel with the Si-Tex T-2041 4kW Color Radar. Combining a compact 25-inch enclosed radome with professional radar functions, this system is ideal for vessels that require dependable performance without the installation space needed for an open-array antenna.

The 4kW transmitter delivers radar coverage up to 36 nautical miles, helping operators detect vessels, shorelines, navigation markers, weather formations, and other potential hazards during daytime, nighttime, or reduced-visibility conditions.

Professional Dual-Range Display

The dual-range function simultaneously presents short- and long-range radar images on the same screen. This allows you to closely monitor nearby traffic while maintaining awareness of distant vessels, coastlines, and developing weather conditions.

The high-visibility 10.4-inch color TFT display provides eight selectable echo colors and supports multiple radar presentation modes, including Head Up, North Up, Course Up, and Waypoint Up.

Clear Target Identification

True Trail technology helps distinguish moving targets from stationary objects such as land and buoys. Interference rejection reduces unwanted radar signals, while target expansion makes smaller or weaker targets easier to identify.

Selectable 24 or 48 rpm antenna rotation provides standard scanning for general navigation and faster updates for high-speed vessels or congested waterways.

AIS and Collision-Avoidance Support

The radar supports AIS target presentation when connected to compatible AIS and navigation equipment. CPA and TCPA alarms help operators evaluate potential collision risks. An optional Automatic Tracking Aid is available for tracking up to 50 radar targets.
